IMPROVEMENT IN HING-ING- TEA-KETTLE COVERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that LELKANAH S. A'rwoon, ofBoston Highlands, in the county of Sufl'olk, and State of Massachusetts,have invented an Improvement in Hinging Tea-Kettle Covers; and I dohereby declare that the following, taken in connection with thedrawings, which accompany and form part of this specificastructcd asshown in the drawings, in plan and in sec-' tion, at D E, two ears, a b,projecting from the edge of the lid, and making, with the ear 0projecting from the kettle, the parts through which the joint-pin dpasses to form the hinge.

The lid is made with two flanges, e f, upon its under surface, theseflanges forming a groove, into which the edge 9 of the kettle extendswhen the lid is closed.

. 5 The cars a (I drop down from the outer flange f, (when the lid isshut,) as seen in red at E, and the water of condensation which reachesthe ears, trickles down upon them, and drops upon the outer Surface ofthe kettle, while, when the lid is thrown up, as seen at E, all thesteam upon the lid condenses, and flows down over the ears.

In my invention, all these products of condensation are returned intothe kettle.

A kettle, or the part thereof embodying the improvement, is shown at A,B, and O; at A, in plan, the lid being thrown back; at B, in section,the lid being thrown up; and at O, in plan, the lid being closed.

- I g denotes the kettle; and h, the lid, or cover. i is the edge aroundthe mouth of the kettle.

Where the hinge is to he formed, this edge is turned outward, formingtwo ears, or bearings, la la, between and to which is jointed, by ahinge-pin, I, an extension, m, of the lid, as seen at A, B, and O; Thisextension is formed of the flange, or ringn, which depends from theunder surface of the lid, the flange continuing around the extension, soas to form an unbroken edge all around the lid, as seen at A.

The end of the flange, at the hinge, shuts within a lip, turned up fromthe kettle, as seen in red at Bf It will be seen, therefore, that thehinge forming part of the lid is entirely within thekettle, so far as itrelates to its under surface, and that no steam-coudensing upon it (whenthe lid is closed) can escape to the outer surface of the kettle at thehinge, as there are no parts of the hinge leading to such outer surfacefrom the under side of the lid, while, when the lid is raised, the waterflowing down toward the hinge must be conducted back into the kettle.

The hinge, so formed, is also much neater in appearance, and the changeadds nothing to the cost of production of the castings. I

The specific construction of the hinge may be modified without departingfrom the spirit of my invention, the essential feature of which consistsin so constructing the hinge that the steam cannot condense and flowalong the parts of the hinge to the outer surface of the kettle.

I claim a kettle, having a hinged lid, the hinge being formedsubstantially as described, to prevent the water of condensation fromescaping to or dropping upon the outer surface of the kettle.
